SPECIFICATION forming part of Letters Patent No. 793,722, dated July 4,1905.

Application filed March 27, 1905. Serial No. 252.300.

To (1.2]- whom, it 171/1/7 concern:

Be it known that I, PETER HnNRIoI-Is, a citizen of the United States,residing at Clarkston, in the county of Asotin and State of VVashington,have invented certain new and useful Improvements in Current-Motors; and1 do doclare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.which form a part of this specification.

This invention'relates to new and useful improvements in current-motorsdesigned especially for pumping water for irrigation purposes; and theobject of the invention is to produce a simple and efficient device ofthis nature which may be mounted upon a float in a stream and soarranged that blades are thrown down into the current of wateralternately first on one side of the float and then on the other for thepurpose of furnishing power to operate a pump.

The invention consists, further, in certain combinations andarrangements of parts, which will be hereinafter fully described andthen specifically defined in the appended claims, and is illustrated inthe accompanying drawings, in which Figure 1 is a perspective view of myimproved current-motor, showing one of the blades inserted in the waterand being acted upon by a current, while the other is raised in positionto return to its rearward position. Fig. 2 is a top plan view of theinvention, and Fig. 3 is an end elevation.

Reference now being had to the details of the drawings by letter, Adesignates a float, which may be anchored in any suitable manner withina stream, and mounted upon said float is a pivotal pin B, as shown inFig. 3 of the drawings, upon which the beam C is pivotally mounted. Saidbeam has laterallyprojecting arms D, which are bifurcated and each ofwhich carries a pivot-pin E, to which the contracted end of ablade-carrying strip F is pivoted. Said strips F are longitudinallyslotted to receive the blades G, which are bolted or otherwise securedto said strips, and

at the extreme forward end of the beam C is a cross-piece K, to whichrods K are fastened, which in turn are fastened to eyes L, mounted uponthe sides of the strips F, thereby keeping the two blades at a fixeddistance from the ends of the cross-piece K, while said blades areallowed to be raised and lowered in a manner which will be presentlyexplained.

Rising from the beam C is a post C, carrying a pivot-pin G in its upperbifurcated end, upon which pin a grooved pulley C is journaled. A chain0 is fastened at one end to an eye 0' upon one of the strips F andpasses over said pulley C, and its other end is fastened to a similareye 0' upon the opposite strip F.

Q designates a rock-shaft, one end of which is journaled in the post Cnear its lower end, and said rock-shaft is journaled also in a bearing 1and at its outer end has an arm Q, projecting at right angles therefrom,to which a chain Q is fastened near the middle portion thereof, and oneend of said chain is fastened at Q to an upright portion of the archedrod R, while the other end of said chain is fastened at (02* to theopposite upright portion of said arched rod, as shown clearly in Fig. 1of the drawings. By means of this chain it will be observed that thethrow of the rockshaft in one direction or-the other may be limited. y

A crank-arm S is also fastened to said rockshaft at any suitablelocation and has secured thereto a cable or chain T, which latter isfastened near its middle portion to the angled end of said crank-arm S,one end of said cable or chain T being fastened to an eye W upon one ofthe strips F, While the other end of the chain is fastened at VV' to theopposite strip F. A counterbalancing-weight V is fastened by a chain tothe end of the crank-arm S.

Mounted in suitable bearings upon the top of the float is a shaft J, oneend of which has a pinion-wheel J adapted to mesh with teeth upon theunder surface of the segment-rack J wherebyas the rack swings back andforth a rocking motion may be imparted to the shaft J and through saidshaft to the crank-arm J to a lever J which may be connected by ratchetmechanism to a pumping apparatus.

The operation of my current-motor is as follows: One blade being loweredinto the water in the manner shown in Fig. 1 of the drawings is carriedby the current until one section of the chain Q becomes taut, afterwhich a further movement of the blade which is in the water will causethe rock-shaft to make a partial rotary movement by reason of the arm Qpulling upon the taut portion of the chain Q which rocking motion of theshaft will cause the crank-arm to be raised with the weight thereon, andafter the weight passes a vertical position it will fall by gravity fromthe opposite side of the beam C and cause the blade to be raised fromthe water. As the weight falls the adjacent blade will fall by gravityinto the current and be carried by. it and the operation is repeated,the counterbalancing-weight being first thrown to one side of the beamand then to the other and by so doing causing the blades to alternatelydip into the current upon opposite sides of the float. The swingingmovement of the beam, carrying the curved segment-rack therewith, willimpart a rocking movement to the shaft J, and through its connections apump (not. shown) may be operated by the employment of a simple form ofratchet feeding device, thus affording a simple and efIicient means forraising water for irrigating or other purposes.

While I have shown a particular form of apparatus illustrating myinvention, it will be understood that I may vary the details of thesame, if desired, without in any way departing from the spirit of theinvention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters ,Patent, is-

1.. A current-motor comprising a float, a swinging beam pivotallymounted thereon, hinged blades mounted upon said beam, a rockshaftcarried by the beam, a chain secured to a projection of said rock-shaftand provided at its ends with suitable anchorage, a counterbalancingweight secured to said rockshaft, connections between saidcounterbalancing-weight and blades, a rack carried by said beam, ashaft, and a pinion thereon meshing with said rack, as set forth.

2. A current-motor comprising a float, a swinging beam pivotally mountedthereon, hinged blades mounted upon said beam, a rockshaft carried bythe beam, :1 chain secured to a projection of said rock-shaft andprovided at its ends with suitable anchorage, a counterbalancing-weightsecured to said rock-shaft, a chain having connection with saidcounterbalancing-weight and its ends connected one to each of saidblades, as set forth.

3. A current-motor comprising a float, a swinging beam pivotally mountedthereon,

hinged blades mounted upon said beam, a rock blades pivotally mountedupon projections of said beam, a post rising from the beam, a pulleycarried by said post, a chain secured at its ends to said blades, arock-shaft journaled in suitable bearings and having a projecting arm atone end, a chain secured to said arm and anchorage means to which theends of said chain are connected, at crank-arm fastened to saidrock-shaft, a counterbalancing-weight secured to the end of saidcrank-arm, a chain secured to said crank-arm and its ends fastened oneto each of said blades, a rack secured to said beam, and a pinion inmesh with said rack and the shaft carrying said pinion, as set forth.

5. A current-motor comprising a float, a swinging arm pivotally mountedthereon, blades pivotally mounted upon projections of said beam, a postrising from the beam, apulley carried by said post, a chain secured atits ends to said blades, a rock-shaft journaled in suitable bearings andhaving a projecting arm at one end, a chain secured to said arm andanchorage means to which the ends of said chain are connected, acrank-arm fastened to said rock-shaft, a counterbalancing-weight securedto the end of said crank-arm, a chain secured to said crank-arm and itsends fastened one to each of said blades, rods connecting said bladeswith a cross-piccc at the end of said beam, a rack secured to said beam,and a pin ion meshing with said rack and the shaft carrying said beam,as set forth.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.

PETER HENRICI-IS.
